Re: string not touching saddle
It is physically impossible for the string not to touch the saddle at some point with that bridge. You can even see that it is bent over the saddle.....hence it is making contact.
The question is 'where' is it making contact, and if in fact that the bridge is in fact shaped so that the intonation is tweaked to be better by sculpting the shape. If so, maybe the string is contacting more toward the back edge....which would be precisely where I would expect a low E with fixed/compensated intonation to sit.
